Flood control inflation bag material:
Outer bag is made of natural jute fabric or non-woven fabric, canvas, with non-woven material and high molecular water absorbent resin inside. The jute fabric of the outer bag, the non-woven inside, and the high molecular water absorbent resin must be non-toxic, odorless, and pollution-free. Pre-absorption size ≥ 600*400mm; post-absorption bag thickness ≥ 8cm; post-absorption pressure resistance ≥ 1.4KN; time required for bag inflation to full capacity ≤ 300S; pre-absorption weight ≤ 500g; post-absorption weight ≥ 20kg; pH value: 6-9.
